Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed January 15, 1906. Serial No. 296.005.

others skilled in the art to which it pertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

- This invention relates to sash-fasteners.

It has for its object an improved stop adapted to engage with a rack onthe sash of a window and to hold the window-sashlocked in any positionat which it may be placed.

In the drawings, Figure 1 is a perspective with parts broken awayshowing a portion of the sash and lock in engagement therewith, thehandle portion thereof reaching outside of the 'inclosing frame at apoint on thesurface of the extreme inwardly-located portion of thewindow-frame as a whole, the window being assumed to be located at itsouter edge. Fig. 2 is a view of a' slightly-modified form of the rod orhandle member. Fig. 3 is a side elevation of the wedge and rack-engagingmember, showing the slidable relation of one to the other. Fig. 4 is aperspective of the sheet metal case with the sides slightly sprungapart.- Fig. 5 shows a slightly-modified form of the escutcheon fromthat shown in Fig. 1.

The sash 1 is provided with a rack 2, that extends along one edge andpreferably from near the top to near the bottom thereof. The lock iscontainedin a case 3, which may be a substantially square box of anyapproved construction provided with flanges and screw-holes throughwhich screws may be griven to secure it to the casing of the win- Withinthe case is a short rack 4, provided on one face with teeth adapted toengage into teeth of the rack 2. The rear face is inclined to'the frontface and is provided with an inclined groove 5 under an inclinedoverhang 6. Behind the block 4 is a second block a, having its frontface inclined, and this also is provided with a groove 7 and with aflange 8, which engages in the groove 5, whereas the overhang 6 engagesin the groove 7. An-

other groove 9 extends parallel with the rear face of the block a, and agroove 10 extends on the under side parallel with the rear face.

The two grooves 9 and 10 are guides which coact with the guides 11 and12 to direct the rear block in its proper path. The rear block isshorter than the width of the case 3 and is normally pressed toward thehandle side by a spring 13. The handle isarod I), screwed into the rearblock and provided with a stem that extends to the front of the casing,where it engages through an escutcheon 14. Upon the stem at this pointis a notched rib 15,

which engages through an extension in the hole of the escutcheon 14 andwhich while in engagement with the escutcheon prevents the handle frombeing turned. If, however, the handle be pushed inwardly until the ribis out of engagement, the handle may then be turned. Preferably there isa notch 16 in the rib, so that the handle may be thrown out until thetwo racks are in engagement and then turn slightly, and the window willbe locked in position. If the handle be pushed in until the rib 15 isslightly inside the escutcheon, the two racks will now be out ofengagement and if the handle be given a partial turn the two parts willbe held in their new position, and the window may be raised or loweredat will. A stop prevents a full rotation of the handle, and thusprevents the handle from being unscrewed from its place.

What I claim is 1 1. A sash-fastener, having in combination a rackadapted to be attached to the sash, a

casing provided with guide portions parallel with the engaging facethereof, a rack held therein and adapted to engage the rack of the sash,being normally in engagement therewith, the rear face of said rackforming an angle with the plane of its engaging face, a sliding wedgeengaging between the rear face of said last-mentioned rack and theguides within said casing, adapted to force said lastmentioned rack intothe casing and out of engagement with the rack of the sash by movementalong said guides, and means for holding the same in place,substantially as described.
